Herein, the synthesis of two novel (X‐DADAD)_n conjugated polymers comprising phenylene or fluorene X blocks coupled with benzothiadiazole acceptor (A) and thiophene donor (D) units is reported. The designed polymers are explored as absorber materials in organic solar cells and hole‐transport materials (HTMs) in perovskite solar cells (PSCs). The encouraging efficiencies of ≈17% are obtained in PSCs when using fluorene‐containing polymer P2 featuring this material as a promising HTM for the state‐of‐the‐art perovskite photovoltaics.

新型的（X-DADAD）n聚合物，具有苯和芴嵌段，可作为有机和钙钛矿太阳能电池的有前途的电子材料

本文报道了两种新型（X-DADAD）_n共轭聚合物的合成，该聚合物包含亚苯基或芴X嵌段与苯并噻二唑受体（A）和噻吩供体（D）单元。设计的聚合物被用作有机太阳能电池的吸收材料和钙钛矿太阳能电池（PSC）的空穴传输材料（HTM）。当使用含芴的聚合物P2（这种材料作为最先进的钙钛矿光伏材料的有前途的HTM）时，在PSC中获得令人鼓舞的效率，约为17％。
